The Google folks are on the list and undoubtedly will answer, but I'm still curious about what even prompts the question. If it's actually missing glue -- NS records that are under the delegation point -- and the delegating NS RRset does not include any independent NSs, then the protocol itself doesn't have an intrinsic mechanism for forward progress. A resolver should SERVFAIL its client, perhaps with the "Code 22 - No Reachable Authority" extended error code. Are you seeing something that suggests Google DNS is making some additional effort to continue? _______________________________________________ dns-operations mailing list dns-operations@lists.dns-oarc.net https://lists.dns-oarc.net/mailman/listinfo/dns-operations
